Title: Wavelength switchable semiconductor laser
Inventor: HE JIAN-JUN
IPC: H04L69/40
Filed: 2005-10-11
Abstract: A monolithically integrated wavelength switchable laser comprises three coupled Fabry-Perot cavities. The first cavity has a length such that its resonant wavelengths correspond to a set of discrete operating channels separated by a constant spacing. The second cavity has a slightly different length so that only one resonant wavelength coincides with one of the resonant wavelengths of the first cavity over the operating spectral window. The lasing action occurs at the common resonant wavelength. The two cavities are coupled through a third cavity that produces a certain coupling loss and phase relationship in order to achieve an optimal mode selectivity of the laser. In operation, both the first and the second cavities are forward biased to provide optical gains. The second cavity is tuned by varying the refractive index through an electrical means, resulting in wavelength switching among the set of discrete operating wavelengths as determined by the first cavity.

Title: Discontinuous metering of catalysts and process auxiliaries into a gas-phase fluidized-bed reactor
Inventor: KARER RAINER
IPC: C08F10/00
Filed: 2004-04-15
Abstract: Method of metering at least one solid, particulate catalyst into a reactor containing a fluidized bed (11) of particles in an at least partly gaseous medium, in which the catalyst is metered discontinuously at prescribed time intervals into the fluidized bed (11) at at least one metering point (10).  According to the present invention, a fluid stream is firstly introduced into the reactor (5) so that a region having a reduced particle density is formed in the fluidized bed (11) around the metering point (10) and the catalyst is subsequently metered into this region. As a result of the prior introduction of a fluid stream ("preblowing") before the actual introduction of the catalyst, the catalyst can penetrate significantly deeper into the fluidized bed from the metering point due to the reduced particle density and is dispersed better.
